Men's Running Base Layers

First on. Last noticed. Essential in between.

Running base layers are where comfort begins-built to regulate temperature, manage moisture, and move with your body through every session. Whether it's a frosty long run, a pre-dawn tempo, or a transitional spring loop, the right base layer keeps you dry, warm (or cool), and focused on the miles ahead.

Look for lightweight, sweat-wicking fabrics like merino blends or engineered synthetics that insulate without overheating. Seamless construction, close-to-skin fits, and stretch where it matters make movement effortless-even when the pace picks up. From short-sleeve and sleeveless options for layering in warmer months, to thermal long-sleeves and compression tights when winter hits, base layers are built to disappear on the run-but do the work underneath it all.

Gear sorted? Now go the distance in the Nike Pegasus or HOKA Clifton—two icons built to run.
